瑜伽師地論略纂 8.10

8.10

論解意律儀中，「防護乃至所有貪、憂」，此憂非五根起，以憂代苦，其意說苦也。

Where the treatise explains the discipline of the mind, "guarding against... all covetousness and grief": this grief does not arise from the five sense faculties; "grief" is used in place of "suffering," and its intended meaning is suffering.
